In how many different ways, the letters of the word 'ARMOUR' can be arranged?


A) 720

B) 300

C) 640

D) None of the above

Correct Answer:
D) None of the above

Description for Correct answer:
Number of arrangements = \( \large\frac{n!}{p! q! r!} \)

Total letters = 6, but R has come twice

So, required number of arrangements

= \( \large\frac{6!}{2!} = \frac{6 \times 5 \times 4 \times 3 \times 2!}{2!} = 360\)
